Problems solved by technology

However, the shortcoming of plasticized PVC is that in addition to PVC resin, the formula and composition also contain a large amount of plasticizers, a certain amount of stabilizers, lubricants and other additives, especially plasticizers are prone to slipping during use. Surface migration, limited applications in food, special electronics packaging
Extensive use of cooling equipment consumes a large amount of energy, which poses threats and challenges to the sustainable development of human beings

Abstract

The invention discloses application of decabromodiphenyl ethane, antimony trioxide or a combination thereof to improvement of a reflection solar spectrum and cooling performance of a modified polyolefin elastomer functional thin film material. On the basis of not influencing basic performance of an existing material at present, when decabromodiphenyl ethane, antimony trioxide or the combination thereof is added, the modified polyolefin elastomer functional thin film material with the reflection solar spectrum and a more remarkable cooling effect can be obtained. The modified polyolefin elastomer functional thin film material with the reflection solar spectrum, disclosed by the invention, is prepared from the following raw materials in parts by mass: 50 to 80 parts of EVA (Ethylene Vinyl Acetate) resin, 5 to 20 parts of POE (Polyolefin Elastomer) resin, 0 to 5 parts of LDPE (Low-Density Polyethylene) resin, 0.5 to 1 part of zinc stearate, 0 to 10 parts of antimony trioxide, 0 to 5 partsof titanium dioxide, 3 to 30 parts of decabromodiphenyl ethane, 0.5 to 1 part of surface modified polytetrafluoroethylene and 0.2 to 0.5 part of antioxidant.

Description

technical field [0001] The invention relates to a functional polymer material and a preparation method, more specifically to a functional thin film material with reflective solar spectrum modified polyolefin elastomer and a preparation method. Background technique [0002] Polyolefins usually refer to ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene and other α-olefins through homopolymerization or copolymerization A general term for a class of thermoplastic resins obtained by reaction. Due to the rich source of polyolefin raw materials, relatively low price, excellent comprehensive performance, and the common processing methods of thermoplastic resins such as extrusion molding, injection molding, calendering molding, blow molding, etc., it has developed rapidly in recent years and has become the largest production capacity. , Widely used general-purpose polymer materials. The main varieties of polyolefins include polyethylene resin and poly...
